| Zusammenfassung |
| Sequestration of C in soils has a major influence on climate change. Fungi play an important
role in carbon decomposition and sequestration but the effect of soil structure and input
of fresh organic matter (particulate organic matter POM) is still unclear. Fungi is
predominant involved in cellulose decomposition and the priming effect (PE) where
old SOM is decomposed by using fresh carbon as a source of energy. Information
on how soil structure affects colonisation and decomposition of POM and SOM
by fungi could help to get explain processes involved in carbon sequestration and
CO2respiration.
The objective of this study was to get a better understanding on the involvement of fungi
in CO2 emissions arising from soils and to gain information on what factors in the soil are
driving organic matter (OM) decomposition. Experimental data on fungal growth
and carbon decomposition as affected by POM abundance and soil structure were
obtained.
